Out-of-source build

[HarryvL]

Hi, I am trying an out-of-source build and am hitting the following error. Can somebody push me in the right direction, please? Thanks, Harry

Hi, I am trying an out-of-source build and am hitting the following error.

How are you doing that? Something like:

Code: Select all

mkdir build
cd build
cmake ..

Can somebody push me in the right direction, please?

When you do the cmake .. step are any warnings noticed in the output?

[HarryvL]

Indeed, the source code is in FC>FreeCAD and the executable in FC>build. So I do the following:

Code: Select all

cd build
cmake ../FreeCAD -DFREECAD_USE_EXTERNAL_PIVY=1 -DCMAKE_BUILD_TYPE=Release .
make

I get plenty warnings from cmake. It looks like dependent files and directories cannot be found? Do I need set explicit paths to them somewhere?

I went back to latest FreeCAD/FreeCAD master, deleted Anaconda3 and tried an In-Source build using the script on the FreeCAD Wiki. Now I get:

Code: Select all

[  9%] Building CXX object src/Base/CMakeFiles/FreeCADBase.dir/__/zipios++/zipoutputstream.cpp.o
make[2]: *** No rule to make target '/home/harry/anaconda3/lib/libz.so', needed by 'lib/libFreeCADBase.so'.  Stop.
CMakeFiles/Makefile2:674: recipe for target 'src/Base/CMakeFiles/FreeCADBase.dir/all' failed
make[1]: *** [src/Base/CMakeFiles/FreeCADBase.dir/all] Error 2
Makefile:127: recipe for target 'all' failed
make: *** [all] Error 2

How is it possible that the FreeCAD build process looks for an Anaconda3 dependency?

[HarryvL]

Is there a way to reset paths for all dependent libs? Clearly something went wrong along the way.

[Kunda1]

I wonder if you need to do a make clean ?

[HarryvL]

@Kunda1 I am new at this. Is "make clean" a simple command?

Hi @HarryvL.

Indeed some of the clues provided from your feedback indicated your build environment could be a bit borked. Not knowing the details it is hard to suggest something. What would likely work is a fresh install of operating system + installing FreeCAD build dependencies and trying to compile FreeCAD after. If you want to fix your current build environment you would likely need to think about the things you changed in the past and revert some of that.

[HarryvL]

Thanks @triplus I indeed jumped to that conclusion and am currently reinstalling my virtual machine with Ubuntu 16.04. I had so many versions of FreeCAD on my machine that it was bound to go wrong at some point
